Construction method for steel sheet pile cofferdam in dense sand soil stratum
The invention discloses a construction method for a steel sheet pile cofferdam in a dense sand soil stratum. The construction method comprises the following steps that firstly, steel sheet piles on the two opposite sides of the cofferdam are constructed; after a guide frame is adopted for limiting when the steel sheet piles are driven, the steel sheet piles on the two sides are driven into soil; wherein the guide frame comprises a guide frame body and a pressing assembly; the whole guide frame body is of a cuboid structure, a plurality of through installation openings are formed in the top of the guide frame body, the shape and the specification of the installation openings are matched with those of steel sheet piles, the installation openings are alternately and reversely connected, arranged and communicated, and the size of the installation openings is 5-10 mm larger than that of the steel sheet piles; and mounting grooves are formed in the top of the guide frame body at intervals of one mounting hole. The pile forming structure is stable, the driving perpendicularity of the steel sheet pile is guaranteed, and the construction efficiency is improved.
本发明公开了一种密实砂土地层钢板桩围堰施工方法，包括以下步骤：步骤一、施打围堰相对的两侧钢板桩；在施打钢板桩时采用导向架进行限位后，完成两侧钢板桩打入土壤中；其中，所述导向架包括导向架架体和压紧组件；导向架架体，所述导向架架体整体呈长方体结构，其顶部开设有若干贯穿的安装口，所述安装口的形状和规格与钢板桩相匹配，若干安装口交替反向连接排列并连通，所述安装口的尺寸大于钢板桩的尺寸5～10mm；所述导向架架体顶部每间隔一个安装孔设置有一个安装槽。本发明成桩结构稳定，且保证了钢板桩的施打垂直度，提高了施工效率。
